Description
The 12V to 220V High-Frequency Inverter Module (40W) is a compact DC-to-AC power conversion board designed for low-power household and DIY applications. It converts 8V–13V DC battery input into 220V AC high-frequency output, making it suitable for powering small AC loads such as LED bulbs, chargers, and energy-saving lamps.
This inverter uses a high-frequency switching design, allowing for a smaller size and lightweight construction compared to traditional transformers. The modular design also allows multiple boards to be connected in parallel to increase total output power for larger applications.
